Transcript

  • 1. Part 2: Types of Chemical Reactions Objectives For this Lesson
  • 2. Objectives For this Lesson <ul><li>After this lesson you should be able to: </li></ul><ul><li>1. Classify a chemical reaction as composition, decomposition, single replacement, or combustion. </li></ul><ul><li>2. Predict the products of simple composition and decomposition reactions. </li></ul>
  • 3. Objectives cont. <ul><li>3. Use the activity series of metals to produce the products of single replacement reactions. </li></ul><ul><li>4. Write the products of the double replacement reaction between two ionic compounds. </li></ul>
  • 4. 5 Types of Reactions <ul><li>Composition (synthesis) </li></ul><ul><li>Decomposition </li></ul><ul><li>Single Replacement </li></ul><ul><li>Double Replacement </li></ul><ul><li>Combustion </li></ul>
  • 5. Composition (synthesis) Reactions <ul><li>Two or more substances react to form a single substance . </li></ul><ul><li>These reactions usually result in the release of energy . </li></ul>A+ B AB S + O O O O S
  • 6. Your Turn <ul><li>Write a balanced chemical equation for the reaction of: </li></ul><ul><ul><li>solid aluminum with sulfur. </li></ul></ul><ul><ul><li>Water and dinitrogen pentoxide. </li></ul></ul>
  • 7. Decomposition Reactions <ul><li>A single substance is broken down into two or more substances. </li></ul>A+ B AB O O C Ca O O Ca + O O C
  • 8. Try These <ul><li>Write a balanced chemical equation for the decomposition of: </li></ul><ul><ul><li>Aluminum oxide. </li></ul></ul>
  • 9. Single Replacement Reactions <ul><li>One element displaces another element from a compound in a single replacement reaction. </li></ul>A+ BX AX +B Fe + S O O O O Cu S O O O O Fe Cu +
  • 10. Activity Series <ul><li>Whether an element will replace another depends upon how active the elements are. A more active element will replace a less active element. </li></ul><ul><li>See your activity chart to determine which elements are more active than others. </li></ul>
  • 11. Solving Single Replacement Reactions <ul><li>Determine what is being replaced, the metals or nonmetals. </li></ul><ul><li>Look up the elements on your activity series chart, to see if the reaction will take place. </li></ul><ul><li>Write the complete skeleton equation, and balance it. </li></ul>
  • 12. Your Turn <ul><li>Write balanced chemical equations for the reaction of: </li></ul><ul><ul><li>Potassium and Zinc Chloride. </li></ul></ul><ul><ul><li>Chlorine and Hydrofluoric acid. </li></ul></ul><ul><ul><li>Iron and Sodium phosphate. </li></ul></ul><ul><ul><li>Fluorine and hydrochloric acid. </li></ul></ul>
  • 13. Double Replacement Reactions <ul><li>Two ionic compounds exchange cations and anions. </li></ul><ul><li>Hint: “outsides combine, insides combine ”. </li></ul>AX+ BY AY +BX
  • 14. + + O O N O Ag K Cl Cl Ag O O N O K
  • 15. Try these <ul><li>Write a balanced chemical equation for the reaction of </li></ul><ul><ul><li>Lithium iodide and silver nitrate. </li></ul></ul><ul><ul><li>Barium chloride and potassium carbonate. </li></ul></ul>
  • 16. Combustion Reactions <ul><li>A substance burning in oxygen . </li></ul><ul><li>Combustion reactions usually involve hydrocarbons . </li></ul><ul><li>Complete combustion results in the formation of water and carbon dioxide. </li></ul><ul><li>Incomplete combustion results in the formation of soot and carbon monoxide. </li></ul>
  • 17. Examples <ul><li>Write a balanced chemical equation for the complete combustion of Propane, C 3 H 8 </li></ul><ul><li>Write a balanced chemical equation for the incomplete combustion of Propane. </li></ul>
